This house was built by 1850 for Charles Winslow, a mill-owner in the Upper Falls Village of Newton. The house was likely a gable-end Greek Revival home consisting of the two right bays seen today. By 1882, another mill owner, Richard Sullivan, purchased the home and completely renovated it with a square tower, stick-work, double door entry, and a porch. He owned a cotton mill near the river and built workers housing between his house and the mills for his workers and their families.
